Choosing a collection tray: this is how to use our consistency request

Our collection trays are available in three different materials: FRP (fibre-reinforced plastic), PE (polyethylene) or steel. Which of these you use depends on what you want to store. With our consistency request, you can easily find what tray material is best for what you want to store. We will tell you how the request works and what you need to bear in mind. 


The industrial cleaning company J.C. Furbisher  is doing well. So well that it will be upgrading soon and will also want to offer facade cleaning. The caustic soda it will use for chemically cleaning facades will be stored in barrels. It definitely wants to be on the safe side when storing this. The fact that incorrect handling could be legally actionable is also a bit of a worry. The company knows that hazardous substances cannot flow into groundwater and soil under any circumstances. That’s because just a drop of a hazardous substance is enough to pollute up to 1,000 litres of water.

Mr. Furbisher gets smart and quickly realises: It needs a collection tray for the barrels in which it will be storing caustic soda. The question to be answered is: which collection tray is the best one in this case? Size plays a role. But first, Furbisher has to find out what material is the most stable for caustic soda. This is what the consistency request on CEMO’s website does.

Furbisher enters ‘caustic soda’ into the search bar. The results the database returns state which material is good for its tray: for caustic soda, PE collection trays are most suitable at an ambient temperature of up to 40°C, according to the request. Essentially, FRP, PE or steel could be used depending on the liquid. Furbisher can also use the database to check collection tray suitability for any other hazardous substance – from pineapple juice to two-stroke oil!


More questions about buying trays

The path to finding the right collection tray is one that leads to the consistency request – and beyond, to answering the following questions:

  • How many containers are stored?
  • How big are the containers (e.g. canisters, barrels, IBCs)?
  • Is the collection tray volume sufficient?
  • Is storage active or passive?
  • How are the storage containers filled?


How big the collection tray has to be is regulated in the Ordinance on Facilities for Handling Substances Hazardous to Water (Verordnung über Anlagen zum Umgang mit wassergefährdenden Stoffen (VAwS)). Generally, collection trays must be able to hold at least ten percent of the storage volume, or the volume of the largest container stored. In water-protected areas the entire volume must fit into it.


Collection trays – the options

Always choose your collection tray based on the hazardous substance and the quantity. Small steel collection trays and rack trays are available for storing substances hazardous to water. IBC collection trays are mainly used as collection trays for tank containers. Ground protection systems can be expanded modularly and allow you to line any surface size. Sump pallets are collection trays for up to ten 200-litre barrels with general building inspection approval.
